## Question:

How long will it take to plate 5.0 g of {eq}Ni {/eq} using a current of 50.0 A and starting with a solution of {eq}Ni^{2+} {/eq}?

## Electrolysis:

Electrolysis is done to drive the non-spontaneous reduction or oxidation reaction to spontaneity by applying current to the system, thereby supplying electrons. One of the uses of this concept is in electroplating in which a current is passed through a solution of a metal cation and through time, the metal cation is converted to solid metal.

The reduction of nickel(II) ions is:

{eq}Ni^{2+}(aq) +2e^- \to Ni(s) {/eq}

The equation that will be used is:

{eq}m = \dfrac{MIt}{nF} {/eq}
